Well instead of just grabbing a random index, grab the index and each time you display a fact add to that index

//pseudo code
OnClick()
fact = [index]
index ++

//if index goes over array 
if (index < array.length)
   index=0

I dont know what code your using, probably Java for this project. But this would solve it. I assume you know how to implement this if your this far.

Please Elaborate your answer or help me with this

public String[] mMixLetters ={"A","B","C"......................};

public String getColor(){
    String color = "";
    //Randomly select a fact
    Random randomGenerator= new Random();// construct a new random number generator
    int randomNumber = randomGenerator.nextInt(mMixLetters.length);//color.length is the length of index of array
    color = mMixLetters [randomNumber ];

    // fact = randomNumber + "";

    return color;

}

//that's the code and i want to get the array element in sequence not randomly how to modify this??
